Description
2~lC~ 58 BEVERAG~ PACRAGE~
The present invantion relates to beverage - packages and, in particular, to be!verage packages containing leaf tea or yround coffee which are ~- intended to provide an infusion of tea or coffee, respectively.
The production of freshly brewed tea or coffee - involves contacting tea leaves or roast and ground coffee with hot water and separating the beverage from the tea leaves or coffee grounds. Various methods for the production of freshly brewed coffee or tea are well known. For example, tea is prepared traditionally in a teapot, the tea leaves being immersed in boiling water and allowed to stand before ' being poured from the pot. Freshly brewed coffee may be prepared by the continuous passage of hot water through roast and ground coffee contained in a filter and the coffee collected in a jug or other receptacle, or by percolation which involves the continllous recycling of water through the roast and ~, ground coffee.
It has previously been proposed to seal fresh roast and ground coffee or tea leaves in individual ~i 25 air-impermeable packages. For example, cartridges or ¦ capsules containing compacted ground coffee are known 3~ for use in certain coffee making machines which are generally termed "espresso" machines. In the ~, production of coffee using these coffee machines the -~, 30 coffee cartridge is placed in a brewing chamber and hot water is generally caused to pass under pressure through the cartridge, thereby extracting the :s aromatic coffee constitutents from the ground coffee - and producing a coffee beverage.
` 35 Cartridges containing roast and ground coffee in which hot water flows under`gravimetric force through ,~ .
i '~
~ - 2 - 21191 ~8 the cartridge are also known. A cartridge of this ~ general type is described in British Patent No.
; 1397116.
~ The cartridges for use in "espresso" machines and .i 5 those through which watex flows under gravimetric force contain a filter positioned beneath the charge of coffee. In the production of coffee from these cartridges water is generally injected into the coffee containing cartridge through a needle. The cartridge is filled with water which flows through ;
,:i the filter and is collected in a cup or other receptacle.
U.S. Patent No. 4446158 describes a disposable individual beverage forming container and filter unit comprising a flat frame having an apertured centre section, filter layers covering the top and bottom of the frame and being secured thereto, and individual quantities of coffee received in compartments formed ~ in the frame between spider-like centre sections -`i 20 thereof.
U.S. Patents Nos. 4996066 and 5002676 describe cassettes for producing a beverage, such as coffee, ~ for use with a liquid receptacle having an internal - ! locking flange. The cassette includes a plurality of ~! 25 ribs connected to an extending across the ring and ~; separating the interior thereof into a multitude of sections.
It is also well known to package leaf tea or ground coffee in so called tea bags or coffee bags ~.~ 30 which generally comprise leaf tea or ground coffee -~ enclosed between two pieces of a filter material which are sealed around their edges to form a bag.
Both the cartridges or capsules containing ~¦ compacted roast and ground coffee and the tea bags or ~ 35 coffee bags suffer from the disadvantage that in ;- order to obtain a beverage of the appropriate . ~

-~ strength from the cartridge, capsule or bag it is necessary for the leaf tea or roast and ground coffee ~ contained therein to be wetted uniformly so that uniform extraction of the leaf tea or roast and s 5 ground coffee takes place. It is known that the .-~ efficiency of extraction from the roast and ground . coffee depends upon estalishing a uniform water flo,w from the start of the infusion process. As soon as , 4, coffee is wetted, its volume increases such than any .-. 10 voids in the coffee become filled by the expanded ,5 coffee and thereafter water flow is regulated through x-- the coffee bed. Unless, however, the coffee bed is `l uniformly wetted, this condition is never reached. A
t, means must be provided be distribute water flow ::.
. 15 evenly into the dry coffee bed.
We have now developed a beverage package which is . adapted to provide a predetermined flow path for 4~ water into and through the beverage ingredients contained therein which controls the wetting of the 20 leaf tea or roast and ground coffee and thus controls the extraction of the leaf tea or ground coffee to form the beverage.
Accordingly, the present invention provides a ~, semi-rigid beverage package containing one or more 25 beverage ingredients which package comprises a top, a ;.~; bottom and a side wall portion the top and the bottom being made from one or more layers of the same or ~:i different water-permeable materials and at least one ~-.. ; of the top or the bottom of the package being .~. 39 provided with areas formed therein which are impermeable or of varying permeability to the flow of water, whereby, in use, water flows through the 'j package in a pre-determined flow pattern to achieve ~-~ immediate wetting of the total contents of the -~ 35 package.
The flow pattern of water through the package may 2 ~ 7 8 ~ - 4 -- be controlled not only by providing areas in the top of the package which are impermeable or of varying permeability to water, but alternatively or in -~ addition thereto by providing areas in the bottom o~
.i 5 the package which are impermeable or of varying i permeability to water. By limiting the flow pattern -- of the beverage leaving the package, the pressure - drop through the package in the direction of the ~ normal flow of water through the package is increased -~ 10 which causes the water to spread out at right angles ~- to the direction of its normal flow and fill the ,~ package.
The top and bottom of the package are made from the same or different water-permeable materials, preferably a water-permeable synthetic material which is heat sealable. Examples of suitable water-permeable synthetic materials comprise a spun-bonded non-woven polypropylene sold under the Trade Name COROVIN, a spun-bonded polyester sold under the Trade Name REMAY and a spun-bonded nylon web sold under the Trade Name CEREX. Melt blown polypropylene may also be used. Other materials which may also be used include cellulosic materials coated with a material - which is activated by heat, or polyethylene or poly-propylene perforated films.
The areas in the top and/or the bottom of the package which are impermeable to the flow of water ~¦ may be formed by applying heat to a heat sealable ~-¦ water-permeable synthetic material in a predetermined pattern, which treatment, if carried out above the melting point of the synthetic material, will cause ~, the synthetic material to melt and fuse together.
~ Alternatively the impermeable areas may be formed by j laminating an appropriat~ material to the top and/or : .-~ 35 the bottom of the package in a predetermined pattern.
-~I The side wall of the package may be formed from a .l .
~:1 _ 5 _ 2~ 7 . water-permeable material but preferably is formed from a water-impermeable material or a water--~ permeable material treated to modil.y its permeability which thus improves the flow of water through the package since water flows through the side wall of ~ the package in a controlled fashion. Suitable :~ examples of water-impermeable materials for the .~, formation of the side wall are polypropylene, :.~ polyethylene, polyester, etc., or a heat and pressure treated water-permeable material.
. The beverage packages of the present invention may be used in different situations, for example as one-cup filters using gravity, plunging brewing using .
the cafetière system or low pressure brewing using .. 15 pressure pump pots.
., The package of the present invention may be ;, produced in different sizes in order to give i different serving options. For example, a package ~i containing about 30 grams of roast and ground coffee will produce 5 cups of coffee, a package containing about 20 grams of roast and ground coffee will produce 3 cups of coffee, whilst a package containing about 7 grams of roast and ground coffee will produce 1 cup of coffee.

, Figure 6 illustrates a sectional view of a beverage package according to a second embodiment of ;- the invention; and Figures 7A to 7E illustrate a beverage package according to a third embodiment of the invention.
Referring to Figures 1 to 4 of the drawings, a beverage package in accordance with the present invention is generally shown at 1.
The package comprises a top 2 and a bottom 3 ` which are joined by a side wall 4. The top portion ~- has a rim or flange 5 which extends beyond the side wall portion. The flange can also be seen in the plan view of Figure 3 and the side view of the - package given in Figure 4.
In the embodiment as shown in the drawings the .1 base portion 3 has areas 6 which are impermeable to the flow of water therethrough. Water will thus flow through the base portion only in the areas of the base between the portions 6 thereof.
As shown in the section of Figure 4 the beverage ~¦ package of the present invention is filled with a ,¦ 25 beverage ingredient, for example roast and ground ;~l coffee as shown at 7.
~-, The beverage package as shown in Figures 1 to 4 ~l of the drawings is formed using a heat sealable -~ material. The base portion 3 and side wall portion 4 ,,, of the package are formed by press forming a heat ~ sealable material into the desired cup shape using .:i heat and pressure to deform the material, as desired. The matPrial is held for a set period of time above its normal forming temperature and then allowed to cool when it retains the shape of the former. Using polypropylene the forming of the base ~i ; .~
~ _ 7 _ 2~ 78 ;3 and side wall may be carried out at a temperature of ~ 130C at 80 bar pressure for 9 seconds.
-i The areas of the base as shown at 6 are subjected to a higher temperature of above 137C (the melting ~-, 5 temperature of polypropylene) in order to melt the i web and thus form the water-impermeable areas 6.
-~ The shaped hody comprising the base 3 and side wall portion 4 of the package is then filled with the ~j roast and ground coffee 7 and the top 2 of the package heat sealed to the top of the side wall 4, ~ thus completing the package.
-~ The forming of the polypropylene into the base 3 and side wall 4 in a single operation provides a semi-rigid structure and this enables the package to '~
be filled very compactly with the beverage ingredient.
It will be noted that the water impermeabie areas 6 of the base 3 of the capsule are also formed as corrugations and this helps to increase the rigidity of the package.
Referring to Figures 5 and 6 of the accompanying drawings, a second embodiment of a beverage package according to the invention is shown.
The beverage package is generally shown at 10 and ~ has a top 11, a bottom 12 and a side wall portion 13.
i~l 25 As shown in Figure 5, the side wall is formed from a closed pore material to improve the flow of water through the coffee bed. A closed pore material may be produced by using a water-permeable material and subjecting all or a part of the surface to heat and pressure. The side wall is also semi-rigid. The l side wall 13 is formed as shown in Figure 5 with an -`~ inwardly extending rim or flange 14 at the bottom ~-~ thereof and an outwardly extending rim or flange 15 at the top thereof. These rims or flanges are provided for heat sealing to the bottom 12 and top 11, respectively.

The bottom is thus ~il 5 provided with areas 15 which are made water-impermeable by a suitable heat treatment of the - material from which the base 12 is formed. The beverage package is filled with a beverage ingredient :~ 16, as shown.
-~ 10 It will be understood that the bottom 12 of the beverage package is sealed to the rim 14 of the side wall 13 as a first operation, the desired amount of beverage ingredient 16 is then introduced into the package and the top 11 is then sealed into position on rim 15 of the side wall 13, so completing the ' package.
;r'~ Referring to Figure 7A to 7E, a beverage package generally shown at 20 comprises a top 21 a bottom 22 ~' and a sidewall 23. The top 21 has a water-~: 20 impermeable central portion 24. The beverage package . is generally divided into two compartments 25 and 26 j~ as shown in Figure 7E. The compartments are formed -~3 by a conical section of water-permeable material 27 "~ being positioned between the top of the beverage 25 package 21 and the bottom of the beverage package 22. ~:
As will be seen from Figures 7A to 7D the ~, component parts of the beverage package are stacked together in the order as shown and the top of the beveage package 21 heat sealed to the rim 28 of the ~ ~ 30 side wall 23, whilst the combination of the base 22 :-~ and cone 27 are heat sealed to the bottom annular rim 29 of the side wall 23.
